The story relates bugs last week in products from Symantec and Kaspersky and the revelation of a much older bug in F-Prot.

The most serious one, according to the article, was in Kaspersky Anti-Virus 6.0 for Windows Workstations and caused the program to raise repeated allow/deny dialog boxes for various processes. A fix was released a couple days later.

Remaining bugs actually had security implications. The F-Prot bug caused the program not to scan ZIP files, which could allow malware through. Along the same lines, IBM Proventia appliances and ClamAV could fail, in some cases, to scan RAR files.
